A novel ultra-wideband compact slot antenna fed by a grounded coplanar waveguide (CPW) is presented. This antenna is similar to the conventional CPW-fed slot antenna, and a forklike tuning stub and a polygonlike slot are designed in order to increase the operation bandwidth of the antenna. It is inv

Adjusting the slot width in a slot antenna can determine the operating frequency bandwidth. In order to obtain a wider radiation beamwidth, a narrower slot width is needed. This paper uses a CPW tuning stub in the CPW-fed slot antenna to achieยจe this goal. แฎ 1998
## Abstract A new compact configuration of a printed CPWโfed semicircular slot antenna with a CPWโtoโCPW step transition is presented. Its bandwidth is enhanced for ultraโwideband (UWB) operation by combining linear and stepped CPWโtoโCPW transitions along the feed line. Its measured 10 dB return l
extinction ratio could be increased further by a proper choice of splitting ratios of the couplers [10]. The wavelength resolution limit of the OSA also limits a precise measurement of the actual extinction ratio. The minimum possible change in the FSR during tuning of the MZI by this technique was
